什么是限定动词组和非限定动词组?
RT.
英语动词有限定(finite)和非限定(non-finite)两类.
句子中的谓语动词(predicative verb)是限定的;限定动词受人称(person)和数目(number)的限制.此外,还有时态(tense )、语态(voice)和情态(mood)等.例如:
① Good leaders serve the people whole-heartedly.
② Jason is giving a public lecture.
③ Who did it?
④ I would appreciate it if you could do me a favour.
在句子中可以施展其他功能的动词是非限定动词;这些动词具有一般动词的许多特性,但没有“人称”和“数目”的限制.
非限定动词分三种:不定式动词(the infinitive); 分词( the participle); 动名词(the gerund); 分词又分现在分词( the present participle)和过去分词(the past participle).
例如:
⑤ Tom found the prescribed text hard to read.
⑥ Helen has a smiling face.
⑦ Your written English is good.
⑧ Smoking is harmful to health.
⑤里的是不定式动词;⑥里的是现在分词;⑦里的是过去分词;
⑧里的是动名词.
